Connect analog sensors to analog input pin 0 and 1 with 10K ohm resistors used as voltage dividers. Connect a pushbutton or switch to digital I/O pin 2 with a 10K ohm resistor as a reference to ground. 通过10 千欧电
- BLUE AND WHITE Product ID: 772 This new Adafruit shield makes it easy to use a 16x2 Character LCD. We really like the Blue & White 16x2 LCDs we stock in the shop. Unfortunately, these LCDs do require quite a few digital pins, 6 to control the LCD and then another pin to ...
on and LOW turns it off. Therefore, to turn on pin 13, we need to write ‘HIGH’ to it as shown on line 4 using the ‘digitalWrite’ function. In the digital world, a binary value of1means HIGH or ON, and0means OFF or LOW. However, for Arduino we will stick with HIGH and ...

reliably, even under varying conditions. The board's voltage regulator (LDO) is capable of delivering a stable output of 5V and 3.3V, providing ample power for most initial projects. The board's ability to supply power through the MicroUSB connector or to power pinheaders adds to its versati...
